BUTT-BOARD FOR GRAIN-TENDERS.

, Specification of Letters Patent.

Patented Jan. 18, 1916.

Application filed April 26, 1915. Serial No. 23,900.

To all whom it may "concern Be it known that 1, JAMES HARTMAN, a citizen of the United States, residing at Bern, in the county of Nemaha and State of Kansas, have invented new and useful Improvements in Butt-Boards for Grain- Binders, of which the following is a specification.

This invention relates to butt boards or devices for evening the butts of grain in grain binding harvesters.

The invention has for its object to produce a construction under which a butt board which is supported for orbital movement in a plane parallel to that of the binder deck over which the grain is passing is provided with a movable apron or tail piece which is effective in liningup the grain with a great degree of preclsion.

A further object of the invention is to simplify and improve the construction of the frame whereby the butt board is supported for orbital movement.

A further object of the invention is to provide the said carrying frame with a shield also engaging the butt ends of the grain and serving as a guidefor the movable apron.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the "same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the drawings,-Figure 1 is a front view of a portion of the elevator casing and binder deck of a grain binder equipped with the invention. Fig. 2 is a sectional view taken on the line 2-2 in Fig. 1. Fig. 3 is a sectional view taken on the line 33 in Fig. 2. Fig. 4 is a plan view of the binder deck showing the invention applied and adjusted in a somewhat different position than in Fig. 2. Fig. 5 is a sectional view taken on the line 55 in Fig. 4:-

The elevator casing is provided with bearings 17 supporting a rock shaft 18 hav-.

ing an arm or bracket 19 which extends above the binder deck in spaced and substantially parallel relation thereto, said arm or bracket supporting a substantially rectangular frame B comprising inner and outer end members 20, 21 and top and bottom members 22, 23, the latter being extended beyond the end member 21 to support an angular shield 2% having a flange 25 provided with a vertical slot 26.

I The butt board 27 is provided at one end with a bracket 28 which is pivoted on a crank 29 on a shaft 30 which is ournaled in suitable bearings on the elevator casing and which receives rotary motion from some moving part of the machine through the medium of a wheel or sprocket 31 with which it is provided. The other end of the butt board is connected by a link 32 with one arm 33 of a bell crank C which is fulcrumed on the inner end member 20 of the frame B, the other arm 3% of said bell crank being connected by a link 35 with a wrist pin36 associated with the crank 29. Rotary movement of the shaft 30 will thus, through the medium of the crank 29 and the bell crank G and related parts, produce an or bital movement of the butt board in a plane substantially parallel to the plane of the binder deck. The butt board 27 is provided at its tail end with an apron or tail piece 37 which is pivotally connected therewith and which is guided through the slot 26 in the flange portion of the angular shield 24. The latter, being relatively stationary, it follows that when the butt board is in motion, the apron 37 will slide to and fro through the slot 26 and will receive a rocking or vibratory movement whereby it will be caused to impinge on the butt ends of the stalks of grain when moving in the direction thereof. This operation is auxiliary to the butt board proper, the engaging face of which is formed or provided with ratchets 38 for the purpose of effectively engaging the grain butts.

To provide for operation of varying lengths of grain, the frame B which is Copies of this patent may be obtained for of the machine in a customary and well known manner.

It will be seen from the foregoing.de-.

scription, taken in connection with the drawings, that grain passing from the ele- ,vatorover the binder deck will be first engaged by the face of the butt board proper .and next by the tail piece or apron 87. Passing beyond'the range of said apron the butt ends of the grain will be engaged by the .relatively stationary shield 24, whereby any irregularities will be corrected, and the grain will be delivered to the packers in an even and perfect manner.

Having thus described the invention, what is claimed as new, is

1. A frame, a bell crank fulcrumed on one end member of said frame, a shaft supported for rotation and having a crank provided with a wrist pin, a. butt board having a bracket pivoted on the crank, a link connecting the wrist pin' with one arm of the bellcrank, a link connecting the butt board with the other arm of the bell crank, and. means for rotating the shaft having the crank, thereby imparting an orbital movement to the butt board. i

2. Aswingingly supported frame, a bell crank fulcrumed' on one end member of said frame, ashaft supported for rotation and having a crank provided with a wrist pin, a butt board having a bracket pivoted on the crank, a link, connecting the wrist with the butt board and guidedthrough the slot of the shield, means for adjusting the swingingly supported frame and for securing it at various adjustments, and means for actuating the butt board.

4. In a grain binding harvester, a swingif ingly supported frame, a butt board supported for orbital movement, a link connection between the butt/board and the swingingly supported frame, means for effecting adjustment of said frame and for g securing it at various adjustments, a slotted shield carried by the swingingly supported frame and relatively stationary with respect to the butt board,.and a tail piece pivotally connected with thebutt board and jf" guided by the slotted shield;

. In testimony whereof I affix my signature in presence of two witnesses.
